Diese Luecke fuellend finden sich an unterschiedlichen Stellen veroeffentlichte Hilfestellungen und Empfehlungen. This article provides a summary dafztb the author’s key aspects regarding support areas.

New DAfStb Issues 630 and 631 supersede Issues 220 and 240

The support nodes must be checked both in direct bearing and in indirect bearing. Dieser Aufsatz stellt eine Zusammenfassung der nach Meinung der Verfasser wesentlichen Aspekte bezueglich der Auflagerbereiche dar. They have proven to Assistance and recommendations are published at various places in order to fill these gaps. If the primary support node fulfills the nodal strength checks in the case of indirect bearing, the load transfer zone can be reinforced following prescriptive detailing rules.

Kann dieser Nachweis nicht erbracht werden, empfiehlt es sich, die Lastuebertragungszone fuer die mittelbare Lagerung explizit zu bemessen. This is supplemented by considerations on indirect bearing.

These old issues are still being used in structural engineering even more than 26 Issue and 38 years Issue after their last editions. Auflagerbereiche wandartiger Traeger Support areas hetf deep beams Die kritischen Bereiche von wandartigen Traegern sind die Auflagerbereiche. Kann im Falle einer mittelbaren Lagerung der primaere Auflagerknoten nachgewiesen werden, kann die Lastuebertragungszone konstruktiv bewehrt werden.

Furthermore, their application will in future be focused on checking numerical calculations. However, their het urgently required both alignment with current codes and standards EC2 and incorporation of new findings and fields, such as fire design and numerical simulation.

The new editions were reviewed by DAfStb bodies and independent consulting engineers to ensure their immediate practical applicability. Ergaenzt wird dies durch Ueberlegungen zur mittelbaren Lagerung.

Sep 14 8: Both documents are not exhaustive at present. Figures; References; Tables; Pagination: Over time, however, the contents of Issue became increasingly popular.

Hefts Issue [1] and [2] of the German Committee for Reinforced Concrete DAfStb have been intensively used by engineers in day to-day practice since the first edition.

Generally, such values can be Uebertragung phys ; Their design and detailing require particular attention, especially when limits are extended. This paper presents an overview of the new issues and refers to their main contents, newly added parts and background information. The determination of safstb actual mechanical properties of the materials used in building is a central element in the reanalysis of existing load-bearing structures.


Die Auflagerknoten sind sowohl bei unmittelbarer Lagerung als auch bei mittelbarer Lagerung nachzuweisen. Ihre Bemessung und konstruktive Durchbildung beduerfen einer besonderen Beachtung, insbesondere wenn in Grenzbereiche vorgestossen wird. For this reason, several universities contributed to preparing completely new editions that take these changes into account and will be published as Issues and from to supersede the previous publications.

Die kritischen Bereiche von wandartigen Traegern sind die Auflagerbereiche. Issue concentrates on guidance and recommendations for determining internal forces for framed structures, slabs, deep beamsSLS verifications such as deformationand various detailed checks such as splitting tensile or edge stresses occurring under partial-area loading. The first choice document for the detailing of deep beams for decades, 24 DAfStb Heftis nowadays no longer consistent in all issues with the now valid Eurocode 2.
